MobSoul — Give Every Mob a Voice

Turn everyday encounters into conversations. MobSoul lets you speak to Minecraft mobs through your microphone, hear their replies, and build relationships through your actions.

Give a villager a written book and discuss its ideas. Disagree with a stubborn neighbor. Earn a creature’s trust and invite it to follow you on your next adventure. Nearby mobs can also start conversations and talk to one another.

Features

• Hands-free conversations — speak naturally without push-to-talk.
• Distinct voices and personalities — meet friendly, reserved, curious and irritable creatures.
• Memories and friendship — mobs remember recent conversations; gifts build trust, while attacks damage it.
• Book discussions — written-book gifts provide real excerpts for dialogue.
• Companions — trusted mobs can follow, wait or protect you.
• Mob-to-mob conversations — nearby creatures occasionally exchange dialogue.
• Ten languages — English, German, French, Spanish, Italian, Portuguese, Dutch, Polish, Russian and Japanese.
• In-game setup — configure your language, microphone, volume, subtitles and request budget.

Getting Started

Install MobSoul on both the client and server. When you enter a world, add your personal Groq API key, select a language and microphone, and save. Missing language packs download automatically.

Approach a mob, look at it and start speaking. Press F6 to open settings or F8 to mute your microphone. Prefer typing? Use /mobsoul say Your message.

To give a gift, sneak and right-click with a book, apple or emerald. Build enough trust before asking a mob to become your companion.

Requirements

• Minecraft Java Edition 1.21.1
• NeoForge 21.1.251
• Windows x64 for client-side speech
• A microphone and your own Groq API key

Privacy and Limits

Speech recognition and voice synthesis run locally. Recognized text, recent memories and limited game context are sent to Groq to generate dialogue. Your API key stays in your local configuration.

Local speech has no per-request service quota. Groq’s free tier has provider limits, and availability may change. MobSoul includes a configurable request budget and no shared developer key or automatic paid fallback.

Individual voice licenses apply. Japanese Hi-Fi-Captain voices are licensed for personal, non-commercial use.

Alpha Release

MobSoul is currently an alpha. Core gameplay and speech generation have been tested, but voice quality, response speed and recognition accuracy vary with language, hardware and network conditions. Compatibility with large public servers and other mob AI mods requires further testing.
